A motherboard
is a printed circuit board that contains the CPU, memory, expansion slots for peripherals
and responsible for connecting every part of the computer linking all the hardware
together.
It allows the components that process the data to communicate with one
another.

RTC (Real
time Clock): Synchronizes bus operations and other components
CMOS
RAM: Used to store information about computer configuration RTC updated date and

Keyboard controller.
Besides
these, some motherboards like 386 contain extra slot for math coprocessor.
The performance,
multimedia graphics, sound capabilities of the computer are maintained by the motherboard.
If we want to increase the performance of our computer, it can be achieved through
the motherboard either by adding the RAM or replacing the CPU chip on the motherboard.
All components of the system we buy must be compatible with the motherboard. If
our motherboard does not support the upgrading of any component we want, then there
is no choice other than to replace with a new motherboard.
Before
buying a motherboard for our computer we have to make sure that it is compatible
with the CPU of our computer.
